We investigated the interaction of opening pry-off bottles

The items needed for the interaction are a beverage that has a pry-off lid and a bottle opener, or the knowledge of opening a pry-off using an alternative method.

To open a pry-off drink with a bottle opener:

1. Take a firm grip of the bottle, generally around the lower half of where the neck meets the body.

2. Use your other hand to position the bottle opener on the cap

3. Lift up the bottle opener, while holding the bottle down

4. You should hear a pop from the seal breaking, the lid will then come off and the drink may or may not start foaming

Common problems and constraints when opening a pry-off are:

1. There are no instructions for first time users

2. Most of the time there is no why to tell if the lid is pry-off or twist off

3. No bottle opener

4. The opener could slip

5. The bottle could slip

Survey Results

1. 100% of participants stated that pry-off bottles where a problem for intoxicated people

2. 100% of participants reported having difficulty with opening pry-off bottles in the past

3. The majority of participants use an opener for pry-off caps

4. The most common alternative to using a bottle opener is to knock-off the cap on the hard surface like a table

Suggested Improvements

To have a diagram on beer boxes to show users how to open the bottle without an opener. To have a rough texture on the bottle neck to prevent slipping when opening.
